Preheat the oven to 375°
On a lightly flowered surface roll the pizza dough out into a large rectangle. Add the ranch dressing and smooth it out onto the dough, leaving about an inch clear on all sides.
Sprinkle the bacon bits on top of the ranch dressing.
Evenly distribute the shredded rotisserie chicken on top. Lightly season it with salt, pepper and garlic powder.
Evenly sprinkle the cheese on top.
Starting with the long side of the dough facing you, gently roll it up tightly just like you would a jelly roll. When you reach the end, pinch the seam to seal it and fold the ends under to keep everything inside.
Place the Stromboli seam-side down on a parchment paper lined baking sheet.
Brush a thin layer of the beaten egg on top and sprinkle it with Italian seasoning.
Carefully place 2-3” slits on the top of the dough for ventilation and place it into the center rack of the oven for 15-20 minutes or until the dough is cooked all the way through.
Let the Stromboli rest for about 5-10 minutes before slicing and serving. Enjoy!
